Solution

The assertion and the reason are both correct, but they are not directly related.

A syncitium is a type of cell or tissue in which the cytoplasm is not divided into separate cells by intervening cell walls or membranes. In the case of muscle fibers, they are considered a syncitium because they contain multiple nuclei within a single, continuous cytoplasmic mass.

The reason given, that muscle fibers have a large number of parallelly arranged myofilaments in the sarcoplasm, is also correct. Myofilaments are the contractile proteins found within muscle cells. They are organized into a specific arrangement that allows for muscle contraction. However, this fact does not directly explain why muscle fibers are a syncitium.

So, while both the assertion and the reason are correct, the reason does not correctly explain the assertion.
